Northwest Residential Energy Study Reveals Home Energy Usage

Northwest Energy Efficiency Alliance (NEEA), a nonprofit organization working to make area homes more energy efficient, has published the first two in a series of reports that will have a big impact on the future of residential energy efficiency in the Northwest. The Residential Building Stock Assessment (RBSA) is a comprehensive research study of energy consumption in more than 1,600 Northwest residential buildings. It will establish a regional baseline for single-family, manufactured, and multifamily homes that will inform the region’s future energy-planning efforts.

The final RBSA sample consists of households across the Northwest representing the service areas of 99 utilities. Of these, 89 are public utilities, 7 are investor-owned utilities, and 3 are natural-gas-only utilities.

Average Annual kWh per Home by State


This figure shows the average kWh usage per home in Washington, Oregon, Montana, and Idaho.

NEEA is conducting this study on behalf of more than 100 utilities throughout the Northwest region, which consists of Oregon, Washington, Idaho, and Montana. The region’s utilities, the Energy Trust of Oregon, and the Bonneville Power Administration will use the study results to identify opportunities for energy efficiency programs.

“Similar studies were implemented in the early 1990s, and since then much has changed in the way the region uses energy,” says Tom Eckman, manager of conservation resources for the Northwest Power and Conservation Council. “Data collected from the study will provide critical support for the Northwest Power and Conservation Council’s Seventh Power Plan development, as well as updated load shape information for our region.”

Utilities and experts in power planning and energy planning will also leverage the results of the RBSA to design energy efficiency rebate programs to help the Northwest meet its increasing residential energy needs.

The first two reports in the series focus on single-family and manufactured homes, respectively. These reports present a comprehensive view of the current state of residential single-family and manufactured stock characteristics through an understanding of the distribution of energy-consuming equipment and lighting. Some key highlights of the single-family report, titled “Residential Building Stock Assessment: Single-Family Characteristics and Energy Use,” reveal that

  • about 57% of single-family homes use natural gas for space heating, and of these, 49% use natural gas as their primary heating fuel;
  • electricity fuels approximately 55% of the water heating use in domestic hot water (DHW) tanks; and
  • the average single-family home has about 63 plug-in lamp sockets.

The report on manufactured homes is entitled “Residential Building Stock Assessment- Manufactured Homes Characteristics and Energy Use.” Some key highlights of the report on manufactured homes reveal that

Read the two reports described above at the NEEA web site.

  • about 70% of manufactured homes use electricity as their primary fuel for space heating, and about 11% use gas;
  • about 90% of manufactured homes use electricity for DHW;
  • the average manufactured home has about 35 plug-in lamp sockets; 28% of all lamps are CFLs;
  • and the uniformity in manufactured homes across the Northwest region is due largely to preemptive federal standards and the region’s energy efficiency programs.

Building America’s Top Innovations

Innovations sponsored by DOE’s Building America program and its teams of building science experts continue to transform our nation’s home-building industry, leading to more and better high-performance homes.

Building America researchers have worked directly with more than 300 U.S. production home builders and have boosted the performance of more than 42,000 new homes.

In 2012, DOE identified more than 30 game-changing research achievements from the years 1995 through 2012 as Building America Top Innovations. In the future, annual Top Innovations awards will recognize outstanding Building America research achievements. Shining a light on these achievements will encourage the industry to build more energy-efficient, healthier, and durable homes.
